either your connectors need cleaning or maybe a break in the wiring. Is there on spot where both wires come together if so check there.If there is any plugs, pull them apart and clean them with contact cleaner

Purchase a CD player cleaning disc. Try Best Buy

no.
purchas an adapter that will allow you to convert one of your XM channels to an AUX input.

Hi -

Sony CD player Red / White RCA - > CD input RCAs on the Arcam.

From the Arcam Preamp Output RCA's, go to the Bose "Input". From the Bose "Output", you need RCA splitters to make them into four outputs to run your amplifier connections.

The sad part about installing into alot of GM cars is that the Harness is about $100 bucks

You need a Metra GMOS-01

You need a metra 40-GM30 ( Antenna adapter, since the stock plug wont plug into after market radio)

And a Metra 99-2003 ( dash kit

you should be able to buy an adapter at a local store that will hook everything up so you dont have to worry about that problem

Usually the LFE out is only a line out and is not amplified in any way, so first of all is your subwoofer self amplified or not? Cause if not, the LFE output won't be of much use to you. So if it's not self amplified you need an new amplifier to put between the receiver and the subwoofer. Any amp that supports RCA line-in input will do. Even a car stereo amplifier will work provided you can get a 12volt power supply to run it in the house. If the subwoofer is self amplified though, then all you need is to make an adapter cause none are readily available in stores to go from a RCA connector to 2 wires. You can buy a virgin RCA connector that you can wire yourself at The Source, Circuit City, or any electronics store you have locally, or if you have an old RCA to RCA wire you don't need anymore, you can just cut it in half, strip the 2 wires and you got you adapter right there.

My homie had the same problem with his escalade they adapted an rca line adapter from the factory wiring to geta signal to his amplifier and it just wasnt hitting like it should so we installed a new deck and plugged the rca cords right into it and boomboom pow it was hittin like a champ-we figured that the stock premium system that was incoprporated into the truck had some sort of an onboard amp that was filtering the bass from the door speakers and which was limiting the bass output to the rca adapter and thus on down the line to the amplifier- so maybe ya might want to look into getting an aftermarket deck and see if that helps your cause-good luck
